php - pgsql connection

Hi,

I know it's not a PHP3 mailinglist but the question is somewhat related
to pgsql.
I would like to know what's the problem with following line:
$dbConn = pg_Connect( " host=$host user=$user password=$password port=$port dbname=$dbname");

The php variables are filled with the appropriate values.
However, I always get the following error:

Warning: Unable to connect to PostgresSQL server: connectDB() -- connect
() failed: Can't assign requested address Is the postmaster running (with
-i) at 'localhost' and accepting connections on TCP/IP port 'dbname='? in
/usr/users/szoli/public_html/guestbook.php3 on line 61

Thanks in advance
